如果一个系列u1,u2,. u2 n +1构成正态分布总体中的随机样本,则任何线性函数A = S12 n + 1(arur)也将是正态分布的;而且当S(ar 2)= 0时,其均值将为零,当S(ar 2)= 1时,其方差将等于原始总体的方差。如果S(arbr)= 0,则任何其他线性函数B = S12 n + 1(brur)将独立于第一个线性函数分布,在这种情况下,平方和x= A2+ B2将分布为使得超过xise-x/e的任何特定值的机会等于抽样总体方差的两倍,其中c是x的平均值。
If a seriesu1,u2,...u2n + 1constitute a random sample from a normally distributed population, they any linear function A = S12n + 1(arur) will also be normally distributed; moreover its mean will be zero if S(ar) = 0, and its variance will be equal to that of the original population if S (ar2) = 1. Any other liner function B = S12n + 1(brur) will be distributed independently of the first if S(arbr) = 0, and in this case the sum of the squares,x= A2+ B2, will be distributed so that the chance of exceeding any particular value ofxise-x/e, where c is the mean value of x, equal to twice the variance of the population sampled.
